Form component

Abstract

A formwork member, comprising an upper plate (1), surrounding side walls (2), and a lower bottom plate (3), the upper plate (1), surrounding side walls (2), and lower bottom plate (3) enclosing a hollow body, It is characterized in that at least one base layer of the upper plate (1) or the surrounding side walls (2) or the lower base plate (3) is laminated with at least one laminated layer (4), and the laminated layer (4) is laminated with the base layer as a whole. At least one stiffening rib (5) is arranged in the cavity, the upper plate (1) or / and surrounding side walls (2) are made of lightweight materials (6), and the laminated layer (4) is composed of a prefabricated layer and a cast-in-place layer or Consists of prefab and prefab layers. In this way, it is suitable for use in hollow floors, roofs, walls, base plates and hollow bridges of cast-in-place reinforced concrete or prestressed reinforced concrete.

Description

[0001] This application is a divisional application of an invention patent application with the filing date of October 1, 2003, the application number of 200610054606.9, and the title of "a formwork component". (1) Technical field [0002] The present invention relates to a formwork member. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and formwork components. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the application number applied by the ...

Problems solved by technology

However, it is inconvenient to manufacture such formwork components, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high. At the same time, there is no reinforcing structure in the formwork components, so the overall strength and rigidity of the formwork components are relatively poor. It is easy to cause damage to the formwork components, and after being applied to the cast-in-place concrete hollow floor, it cannot participate in the force and transmission of the cast-in-place concrete floor
